This example presents a top-10 programming languages chart as an interactive scatter plot, showing the 2024 market share percentages from `data.csv`. Each language is a black circle positioned on an x/y grid; clicking a circle turns it white with a black outline. The visualization uses React with D3 v7, employing `renderCircles` with `scaleLinear` for axes and click handlers for selection. An SVG pie chart with a legend is also available via `pieChart`, using `pie` and `arc` with `scaleOrdinal` and `schemeTableau10` for coloring.
